Mike works for $12 an hour. A total of 15% of his salary is deducted for taxes and insurance. He is trying to save $700 for a new bicycle. Write an equation to help determine how many hours he must work to take home $700 if he saves all of her earnings?

12h -.15=700

12h +.15(12h)=700

h -.15(12h)=700

12h -.15(12h)=700
